i b all 'LU/hOT/L it may concern Be it known that 1, JOHN Camus, of 56 lVolverhampton' road, \Valsall, South Staffs, England, engineer, have invented certain new and useful Improvements in and Belatthe Tires of Wheels of Vehiclcsor the of which the following is a specificabut may be of any other figure in section, and which isresilient and preferably made of rubber. The section is provided with a chamber 2 and means are provided forclosing this chamber independently of the rim, or any portion of the wheel, and such means are also preferably used for the purpose of fastening the section to the; wheel.

chamber preferably has an opening in bottom (or side next the wheel) andsuch opening is preferably smaller than the :bot-

:Llke,

The object of, my invention has been to provide an improved resilient tire for vehicles which shall have, among others, any or all of the following advantages: That while it shall normally have pneumatic action, it shall be capable of valuable service, even though it be punctured; thatit shall. be capable of being made in sections so that an injured section can be replaced without requiring the replacement of the whole tire, that while. it. has a pneumatic action such tially flat, and preferably provided with grooves l and 5. A'fastcning plate is preferably situated within the chamber and is preferably forced up through the opening in the bottom of the chamber. The fastening late preferably has a. mushroom or other suitably shaped head 6, and a reduced neck 7 which is adapted to fit the opening. The

that pumping head of the plate has beads or rims 8 which atatmosphereic pressure, so

bottom of the chamber. A bolt 12 is threadsufiicient rcsilienc Y to'bear the weight of the cd into the head and it carries a coverfplate matic action; and that the air chambers in ment, and by turning the cover plate'on the bolt 12, the upper and lower surfaces of the bottom wall of the chamber areclamped be.- tween the mushroom head and the cover plate so as to make a substantially air-tight connection. The ribs and grooves aid in making the connection tighterp They also assist the grip of the fastening on the rubber stud to resist lateral strains. The

contact with the rim ,or other part of the wheel; and to such ends my invention consists in the resilient tire hereinafter speci-' In the accompanying drawings I have illustrated the invention by the form best known to me, but such form is to be regarded as typical of many possible forms, and my invention is not to be confined theretoln the accompanying drawings l igure 1 is a longitudinal sectional elevation of the illustrated embodiment of my invention: Fig. 2 is a cross-section on the line a-b of 1; Fig. 3 is a cross-section of the stud similar to that shown in Fig. 2, but disconnected from the wheel; Fig. at is a section on the line c-ci of Fig. 1; Fi g. 5 is an elevation of the fastening device of Figs. 2 and 3: Fig. 6 is a perspective view of a series of single sections of the tire disconnected from the rim; and Fig. 7 is a cross-sectional clevation of a stud or tire section in which the fastening to the rim is by means of a bolt rivet-ed to the fastening plate, this'construo tion being more specially adapted for light vehicle wheels. i

In. the construction illustrated in Figs. 1 to 5, I have provided a section 1, which is shoun as rectangular in luwizontal section between the nut 16 and the run of the wheel, as shown in erably flanged so as to engage telly 15. The Fig. 2; is preftheouter sides strains.

While the tire sections may be made with a single chamber in each section, in the pres ent instance I have shown a section to contain three chambers and I find it unnecessary to fasten the section at each chamber to.tho rim. 1, therefore, provide the construction shown in Fig. a for closing the opening into the chambers not requiring the fastening. Such means, in the present instance, consists 'of a plug in the form of a shell whose upper end is flanged over the upper surface of the bottom wall of the chamber, andiwhose lower end is closed by tom, and the bottom is preferably substan are adapted to fit the groovesel and 5 in the 13 with which it also has threaded engagc-.

bolt '12 is passed through the rim of the of the studs and supported against lateral The the

rhcel. A washer 1'? is preferably interposed a bottom 11 which extends over the lower surface of said bottom wall. q

The adjoining sections are preferably provided with recesses 18 into which projections 19 are dove-tailed.

In the formshown in Fig. 7, the bolt 12 is riveted at its upper beaded end to the fastenin late 6 within the chamber, in-

stead of 'air chamber, a portion of said sealing means being within the interior of said section and said sealing means accomplishing, its sealing function independently of the rim, and a device directly secured to said sealing means i and adapted to fasten the tire to the Wheel.
